BACKGROUND

The present application relates generally to the field of joints orcouplings for a fluid conduit. The present application relates morespecifically to a quick connect and quick disconnect system for a fluidcoupling.

Connecting and disconnecting water lines to and from a faucet may bedifficult, as it is usually done in a dark, confined space under acabinet. Threaded connections are often over-tightened which may lead toleaks, for example, via over-compression of an o-ring or cracking of thefitting. Conventional quick connectors may require properly aligning thepieces or actuation of small elements, which may be difficult to dounder a cabinet. Other quick connectors may be difficult to disassemble,which may make repair or replacement of the faucet difficult.Accordingly, there is a need for an improved quick connect and quickrelease system.

DETAILED DESCRIPTION

Quick Connect Assembly

Referring generally to FIGS. 1-14, and particularly to FIGS. 1 and 2, aquick connect assembly 10 and components thereof are shown according toan exemplary embodiment. The quick connect assembly 10 includes a maleassembly 18 and a female assembly 19 (shown as a Tee) having a receiver70. The male assembly 18 includes a fitting 20 secured to a fluidconduit (line, pipe, etc.), shown as a hose 12. A clip 40 is coupled tothe fitting 20 and releasably couples the male assembly 18 to the femaleassembly 19. A seal 14 is coupled to the fitting 20 and seals betweenthe male assembly 18 and the female assembly 19.

When assembled, the fitting 20 and the receiver 70 are connectedtogether such that fluid (e.g., water) may flow from the hose 12 intothe receiver 70. Another assembly may be installed into another end ofthe Tee, thereby providing a sealed fluid pathway from one fluid conduitto another. While the receiver 70 is shown to be a Tee, the receiver mayhave any number of ends (e.g., a single ended terminal, a two-endedcoupling, a four or more ended distributor, etc.).

Before discussing further details of the quick connect assembly and/orthe components thereof, it should be noted that references to “front,”“back,” “rear,” “upward,” “downward,” “inner,” “outer,” “right,” and“left” in this description are merely used to identify the variouselements as they are oriented in the FIGURES. These terms are not meantto limit the element which they describe, as the various elements may beoriented differently in various applications.

It should further be noted that for purposes of this disclosure, theterm “coupled” means the joining of two members directly or indirectlyto one another. Such joining may be stationary in nature or moveable innature and/or such joining may allow for the flow of fluids,electricity, electrical signals, or other types of signals orcommunication between the two members. Such joining may be achieved withthe two members or the two members and any additional intermediatemembers being integrally formed as a single unitary body with oneanother or with the two members or the two members and any additionalintermediate members being attached to one another. Such joining may bepermanent in nature or alternatively may be removable or releasable innature.

Referring to FIGS. 3 and 4, a fitting 20 is shown, according to anexemplary embodiment. The fitting 20 is shown to extend axially along anaxis A and to include a first end 22 that is axially spaced from asecond end 24 that is configured to be secured to the hose 12. Forexample, the second end 24 includes a plurality of barbs 26 over whichthe hose 12 may pass, and then a clamp 16 (see, e.g., FIG. 10) may becrimped onto the hose 12 and the fitting 20.

The fitting 20 has an outer periphery having a first diameter D1 and arecessed body portion 28 having a second diameter D2, which is less thanthe first diameter D1. The fitting 20 defines a first groove 30 (e.g.,annular groove, slot, etc.) having a third diameter D3, which is lessthan the second diameter D2. The first groove 30 is shown to be annular.The fitting 20 is further shown to define a second groove 32 (e.g.,annular groove, slot, etc.) located between the first groove 30 and thefirst end 22. The second groove 32 is configured to receive a seal 14(e.g., o-ring, sealing element, etc.). A passageway 34 (e.g., bore,hole, etc.) configured to permit fluid to flow through the fitting 20extends axially through the fitting 20. The fitting 20 may be made ofany suitable material. For example, the fitting 20 may be made of metal,brass, stainless steel, composite, plastic, polyphenylsulfate, etc.

Referring to FIGS. 5-9, a clip 40 is shown, according to an exemplaryembodiment. The clip 40 includes a base 42 through which axis A is shownto pass. According to the exemplary embodiment shown, the base 42 has a“C” shape that extends circumferentially substantially around the axisA. The base 42 defines an opening 44 and a gap 46 extending radiallyfrom the opening 44 through the base 42. The diameter D3 of the fitting20 at the first groove 30 and the base 42 are configured to allow thefitting 20 to be forced through the gap 46 and be retained in theopening 44 of the clip 40. Accordingly, the clip 40 may be snapped ontothe fitting 20. Further, the axial length of the first groove 30 isshown to be similar to the thickness of the base 42, thus limiting axialmovement of the clip 40 when coupled to the fitting 20. According toanother embodiment, the base 42 may be of other suitable shapes. Forexample, the base 42 may extend fully around the fitting 20. The clip 40may be formed of any suitable material, e.g., metal, plastic,polyoxymethylene, etc.

According to the exemplary embodiment shown, the clip 40 includes a wing48 (shown as a first wing 48 a and a second wing 48 b) that extendssubstantially axially from the base 42. According to the exemplaryembodiment shown, the first wing 48 a and the second wing 48 b areradially or diametrically opposite one another. Briefly referring toFIGS. 8 and 9, an inner surface 50 of the wings 48 extend radiallyoutward as the wings 48 extend axially from the base 42. Accordingly,when the wings 48 are forced radially towards one another, the wings 48do not interfere with the fitting 20. Further, the thickness of the base42 is shown to decrease to a minimum 52 between the wings 48, therebyfacilitating flexing of the base 42 when the wings 48 are forcedradially together. Accordingly, when the first and second wings 48 a, 48b are pushed towards one another (e.g., squeezed), the wings 48resiliently deflect towards one another. While the exemplary embodimentis shown to have two wings 48, it is contemplated that the clip 40 mayhave one, three, or more wings 48.

A lug 54 (shown as a first lug 54 a and a second lug 54 b) extendsradially from each of the wings 48. According to the embodiment shown,the lugs 54 have a delta shape having a narrow end 56 proximate the base42 and a broad end 58 distal the base 42. Briefly referring to FIGS. 7and 8, the end of the lug 54 that is distal the base 42 (e.g., the broadend 58) extends radially and axially away from the wing 48 so as todefine an undercut 60.

Referring to FIG. 10, a male assembly 18 is shown according to anexemplary embodiment. The male assembly 18 is shown to include thefitting 20 secured to the hose 12 via crimped clamp 16. The clip 40 iscoupled to the fitting 20, and the wings 48 extend over the recessedbody portion 28 of the fitting 20. The seal 14 is coupled to the fitting20 between the first end 22 and the clip 40.

Referring to FIGS. 11-14, a female assembly 19 (shown as a Teeconnector), is shown according to an exemplary embodiment. The femaleassembly 19 is shown to have three receivers 70, which are eachconfigured to couple to a male assembly 18. According to otherembodiments, the female assembly 19 may have a different number ofreceivers 70, and the other ends of the female assembly 19 may have adifferent type of connection (e.g., threaded, bayonet, friction, etc.).Further, as the male assemblies 18 may plug into multiple sides of thefemale assembly 19, it is contemplated that fluid may flow in eitherdirection through the male assembly 18.

The receiver 70 includes an end 72 and a sidewall 74 extending axiallyfrom the end 72. The sidewall 74 at least partially defines a bore 76.According to the exemplary embodiment (as best seen in FIG. 13), thesidewall 74 includes a first portion 78 that is proximal (e.g., nearer,closer, etc.) to the end 72 and a second portion 80 that is distal(e.g., farther) from the end 72. As shown, the second portion 80 has anarrower diameter than the first portion 78. When the clip 40 is in theinstalled position, the seal 14 seals (e.g., sealingly engages) betweenthe fitting 20 and the second portion 80 of the sidewall 74.

An aperture 82 (show as first aperture 82 a and second aperture 82 b)passes from the bore 76 through the sidewall 74. According to theembodiment shown, the aperture 82 is defined by the sidewall 74 and alip 84, and the aperture 82 passes radially outwardly through thesidewall 74. Referring briefly to FIG. 14, the lip 84 extends outwardlyfrom the bore 76 toward the end 72.

When the clip 40 is in an installed position (see, e.g., FIGS. 1 and 2),the lug 54 extends at least partially through the aperture 82. Accordingto the exemplary embodiment shown, the first lug 54 a at least partiallyextends through the first aperture 82 a, the second lug 54 b at leastpartially extends through the second aperture 82 b, and the lips 84 a,84 b are seated in the respective undercuts 60 a, 60 b. Accordingly,when the clip 40 is in the installed position, axial force trying topush the clip 40 out of the receiver 70 (e.g., water pressure in thequick connect assembly 10, pulling on hose 12, etc.) will force the lip84 into the undercut 60, thereby preventing the quick connect assembly10 from disassembling. Thus, the quick connect assembly 10 inhibits auser from uncoupling the clip 40 and the receiver 70 before fluidpressure has been relieved from the system (e.g., hose 12 has beendrained).

The receiver 70 is further shown to include a guide 86 (shown in FIG.14) extending radially inward from the sidewall 74 into the bore 76. Theguide 86 is configured to rotationally urge the lug 54 toward theaperture 82 as the clip 40 is moved from an uninstalled position to theinstalled position. As shown, the guide 86 includes a narrower end 88that is closer (e.g., nearer, proximal, etc.) to the end 72 of thereceiver 70 and includes a broader end farther (e.g., distal, etc.) fromthe end 72 of the receiver 70. Accordingly, as the clip 40 is moved fromthe uninstalled position to the installed position, the guide 86 rotatesthe clip 40 in response to the axial force, thereby orienting the lug 54to the aperture 82. According to the exemplary embodiment shown, thefirst guide 86 x and the second guide 86 y are located radially oppositeone another, and both the first guide 86 x and the second guide 86 y arelocated substantially orthogonal to the first aperture 82 a and thesecond aperture 82 b. According to one embodiment, the plurality of lugs54 and the plurality of apertures 82 are evenly spaced around axis A.Thus, each lug 54 is guided to an aperture 82 in response to axialforce, without the user needing to actively or consciously try to orientthe lugs 54 and the apertures 82.

Assembly and installation of the quick connect assembly 10 will now bedescribed according to an exemplary embodiment, with reference to theexemplary embodiment shown in the figures. The fitting 20 is coupled tohose 12. The second end 24 of the fitting 20 is inserted into the hose12, and the clamp 16 is crimped over the hose 12 and barbs 26 to securethe fitting 20 to the hose 12. The base 42 of the clip 40 is coupled tothe fitting 20 by inserting the base 42 into the first groove 30. A seal14 is seated into the second groove 32.

The male assembly 18 is then inserted into the female assembly 19. Thefirst end 22 of the fitting 20 is pushed axially (e.g., positive axialforce) into the bore 76 of the receiver 70, past the end 72 of thereceiver 70. The narrow end 56 of the lug 54 will end up on one side(e.g., left or right, clockwise or counterclockwise, etc.) or the other(e.g., right or left, counterclockwise or clockwise, etc.) of thenarrower end 88 of the guide 86. Which side the narrow end 56 ends up onis not necessarily important in the embodiment shown; however, thegeneral narrowness of the narrow end 56 and the narrower end 88facilitates the two ends 56, 88 being offset from one another andreduces the chance that the two ends 56, 88 will end up abutting oneanother in a stalemate. As the male assembly 18 is further forcedaxially into the receiver 70, the angled interfaces of the guide 86 andthe lug 54 cause the clip 40 to rotate such that the lugs 54 are guidedto the apertures 82.

As the clip 40 is installed into the receiver 70, the wings 48 aredeflected radially toward one another by the sidewall 74. As describedabove, the angled inner surface 50 of the wing 48 and the reduceddiameter D2 of the recessed body portion 28 allow the clip 40 to deflect(e.g., flex, collapse, etc.) to at least partially within the outerperiphery of the fitting 20, thereby facilitating insertion of the clip40 into the receiver 70.

When the lugs 54 axially and rotationally reach the apertures 82, theclip 40 and the wings 48 resiliently return to a relaxed state, and thelugs 54 at least partially extend through the apertures 82. Contactbetween components may cause an audible noise (e.g., a click) or maycause a tactile or haptic feeling that is/are observable by the user tocommunicate that the wings 48 have returned to the relaxed state and/orthat the lugs 54 have at least partially extended through the apertures82. A negative axial force may be applied to the male assembly 18 (e.g.,by pulling on the hose 12, by creating fluid pressure in the quickconnect assembly 10, etc.). The negative axial force causes the lips 84to seat into the undercuts 60. The clip 40 is in an installed position,and during installation, the seal 14 has sealingly engaged the sidewall74, creating a sealed fluid pathway through the quick connect assembly10.

Disconnection of the quick connect assembly 10 will now be describedaccording to an exemplary embodiment. According to an exemplaryembodiment, fluid flow to the quick connect assembly 10 should bestopped, and fluid pressure in the quick connect assembly 10 should berelieved. The lips 84 are unseated from the undercuts 60 by moving theclip 40 in a positive axial direction (e.g., further into the bore 76,etc.). The angles of the undercut 60 and the lip 84 are configured totransfer radial forces into axial forces. For example, a user maysqueeze (e.g., apply a compressive force) the lugs 54 together (e.g.,toward one another), and the interface of the undercut 60 and the lip 84causes at least some of the force to be transferred into a positiveaxial force. When the broad end 58 of the lug 54 has moved over the lip84, the clip 40 and/or the wings 48 may deflect such that the lugs 54may move radially to within the bore 76. When the components of the clip40 are within the bore 76, the clip 40 may be moved axially (e.g.,negative axial force) toward the end 72 of the receiver 70 and out ofthe receiver 70. For example, the male assembly 18 may be withdrawn fromthe receiver 70 by pulling on the hose 12.

Quick Connect Release Assembly

Referring generally to FIGS. 15-23, and particularly to FIG. 15, a quickconnect release assembly 100 and components thereof are shown accordingto an exemplary embodiment. In very low visibility or very space-limitedsituations (e.g., a small, dark bathroom cabinet, etc.), a user maydesire a disconnect mechanism for a fluid coupling that is easier tolocate and operate than the standard disconnect procedure of compressinglugs 54 of male assembly 18. In these circumstances, use of quickconnect release assembly 100 may be particularly helpful. Quick connectrelease assembly 100 includes quick connect assembly 10 and all thecomponents it comprises (e.g., male assembly 18 and female assembly 19).Release assembly 100 also includes quick connect release adaptor 110,which may be installed over and surrounding the female assembly 19 ofquick connect assembly 10 in order to facilitate ease of decoupling ofmale assembly 18 from female assembly 19.

Turning now to FIG. 16, a perspective view of quick connect releaseadaptor 110 is shown, according to an exemplary embodiment. Quickconnect release adaptor 110 may be a separate component from maleassembly 18 and female assembly 19, and thus may be installed wheneverconvenience is desired (e.g., the low visibility or space-limitedscenarios described above). Quick connect release adaptor 110 includes aplurality of adaptor bores 120, a plurality of release tabs 130, and aclamshell hinge 140. For example, as depicted in FIG. 16, releaseadaptor 110 may contain three bores arranged in a Tee connector shape,with each bore terminating at a common center point, to match thecontours of female assembly 19. Clamshell hinge 140 permits thesymmetrical halves of release adaptor 110 to be maneuvered into an openconfiguration in order to receive and retain female assembly 19. Theopen configuration of release adaptor 110 will be discussed in greaterdetail in FIGS. 18 and 20 below. Still referring to FIG. 16, adaptor 110further includes flanges 150, which function to connect the adaptorbores 120 that are not connected via hinge 140. Flanges 150 additionallycontain closure pegs 160 and peg receiver holes 170, features which mayfunction to retain release adaptor 110 in a closed configuration. Theseretention features will be discussed in greater detail in FIGS. 18-19below.

Referring now to FIG. 17, an elevation view of the quick connect releaseadaptor 110 is shown, according to an exemplary embodiment. A pluralityof release tabs 130 may correspond with the number of adaptor bores 120such that each bore 120 has a pair of tabs 130. In various embodiments,release tabs 130 may be sized such that a user may easily locate thetabs without having actual visibility of adaptor 110. As shown in FIG.17, each pair of release tabs 130 may be located diametrically from eachother such that a user may easily apply a compressive force (e.g., usinga thumb and a forefinger) to the tabs. In other embodiments, releasetabs 130 may be arranged in a variety of different orientations.

Still referring to FIG. 17, while in a neutral position, release tabs130 may be angled slightly outward from adaptor 110 with respect to themajor axes of bores 120. Tabs 130 may additionally exhibit somespring-like qualities to permit tabs 130 to resiliently deflect throughapertures 135 when a compressive force is applied (see FIG. 18 forfurther description of apertures 135), and to snap back to the neutralposition when the compressive force is removed. In various embodiments,each release tab 130 may also comprise a corresponding tab protrusion180. Tab protrusion 180 may function to transfer a compressive force auser exerts on release tab 130 to lugs 54 of male assembly 18. Bycompressing lugs 54, the user may decouple male assembly 18 from femaleassembly 19. This function will be discussed in greater detail belowwith respect to FIGS. 22-23.

Referring now to FIG. 18, a perspective view of quick connect releaseadaptor 110 is shown in an open configuration, according to an exemplaryembodiment. As described above, release adaptor 110 may be comprised ofsymmetrical halves joined via clamshell hinge 140. For example, as shownin FIG. 18, each half of adaptor 110 has 180° rotational symmetry aboutthe center point of the part such that when adaptor 110 is maneuvered toa closed configuration, each closure peg 160 of flange 150 may mate withpeg receiver hole 170 of flange 150 on the other symmetrical half. Eachsymmetrical half of adaptor 110 may comprise a common sidewall 125 thatmay partially define the plurality of bores 120. As described above,bores 120 may terminate at a common center point, and sidewall 125 maybe shaped to match the contours of female assembly 19 (e.g., extrudedbosses on adaptor 110 may correspond to recesses on female assembly 19,etc.). Sidewall 125 may also define a plurality of apertures 135, witheach aperture 135 corresponding to a release tab 130. The plurality ofrelease tabs 130 may be joined at a common point (e.g., the centerpoint) of each symmetrical half of adaptor 110. As described above,release tabs 130 may exhibit spring-like features in the presence ofcompressive forces, and the common point may also serve as a fulcrum fortabs 130 as they deflect relative to apertures 135.

Turning now to FIG. 19, a perspective view of quick connect releaseadaptor 110 in a partially closed configuration is shown, according toan exemplary embodiment. As described above, closure pegs 160 mayfunction to retain release adaptor 110 in a closed configuration. As auser moves adaptor 110 from an open configuration to a closedconfiguration, the flanges 150 that may include closure pegs 160 and pegreceiver holes 170 move closer to each other. As flanges 150 move closeruntil they are ultimately flush, the flared ends 165 of closure pegs 160may pass through peg receiver holes 170. Once flanges 150 are flush witheach other, flared ends 165 may fully protrude from receiver holes 170.In some embodiments, flared ends 165 may provide a compressive force onflanges 150, serving to retain adaptor 110 in a closed configuration.Although adaptor 110 is depicted with a pair of closure pegs 160 andcorresponding peg receiver holes 170, in other embodiments, a pluralityof pegs 160 and holes 170 may be utilized to retain adaptor 110 in aclosed configuration. In still other embodiments, various othermechanisms may be utilized to retain release adaptor 110 in a closedconfiguration (e.g., threaded fasteners, friction fittings, etc.).

Quick connect release adaptor 110 may be formed or constructed from avariety of materials and in a variety of manners. For example and in oneembodiment, adaptor 110 may be of unitary construction (i.e., all onepiece), where adaptor 110 may be molded, extruded, cast, formed/machinedetc. In another embodiment, instead of comprising symmetrical halves ofa unitary part, adaptor 110 may be fabricated as separate components.The separate components may then be permanently joined to form adaptor110 as a unitary part, or the components may be temporarily joined toform adaptor 110 when quick connect release assembly 100 is in a fullyinstalled state. Accordingly, adaptor 110 may be constructed from anysuitable material, including, but not limited to, plastic, composites,metal, metal alloys, and/or any combination thereof. By fabricatingadaptor 110 as a separate component from female assembly 19, materialfor adaptor 110 may be cost and performance optimized for the functionsof adaptor 110 alone, without regard to the needs of female assembly 19.In addition, because adaptor 110 is fully separable from female assembly19, any failure of adaptor 110 does not compromise the functionality orsafety of the hydraulic connection between male assembly 18 and femaleassembly 19.

Referring now to FIGS. 20-21, perspective views of quick connect releaseassembly 100 in partially assembled states are shown, according toexemplary embodiments. Referring specifically to FIG. 20, quick connectrelease adaptor 110 is shown in an open configuration, with femaleassembly 19 aligned vertically above adaptor 110. Specifically, femaleassembly 19 is aligned such that the axes of bores 76 of female assembly19 are aligned parallel with the axes of bores 120 of adaptor 110. Maleassembly 18 is depicted as axially aligned with one of the three bores120 of adaptor 110. Turning now to FIG. 21, female assembly 19 islowered vertically into adaptor 110 such that the bores 76 of femaleassembly 19 are substantially concentric to the bores 120 of adaptor110. Once adaptor 110 has been maneuvered to a closed configuration,male assembly 18 may be coupled to female assembly 19 as described inthe sections above, specifically resulting in lugs 54 of male assembly18 partially extending through the apertures 82 of female assembly 19.In another embodiment, male assembly 18 may first be assembled intofemale assembly 19 to form quick connect assembly 10. Quick connectassembly 10 may then be assembled with quick connect release adaptor 110to form quick connect release assembly 100.

Referring now to FIGS. 22-23, elevation views of quick connect releaseassembly 100 in partially disassembled states are shown, according toexemplary embodiments. In order to disassemble quick connect releaseassembly 100, the user may first stop the fluid flow to the quickconnect disconnect assembly 100, and relieve the fluid pressure withinassembly 100. As shown in FIG. 23, as a user squeezes release tabs 130(e.g., applies compressive force 190), the tabs pass through apertures135 and force is transferred from release tab protrusions 180 to lugs54. As compressive force 190 causes the lugs 54 to move together (e.g.,toward one another), the interface of the undercut 60 and the lip 84causes at least some of the force to be transferred into a positiveaxial force. When the broad end 58 of the lug 54 has moved over the lip84, the clip 40 and/or the wings 48 may deflect such that the lugs 54may move radially within the bore 76, which may be surrounded by bore120 of release adaptor 110. Continuing the disconnect process andreferring now to FIG. 23, when the components of the clip 40 are withinthe bore 76, the clip 40 may be moved axially toward the end 72 of thereceiver 70 and out of the receiver 70. For example, the male assembly18 may be withdrawn from quick connect release assembly 100 by pullingon the hose 12.
